AUTOlI AT IC TRAIN CONTROL.

Application fled Ilrtll 23, 1920. Serial H0. 9,130.

To all whom, it may concern: p t- Be it known that L PAUL J sluu' m acitizen of the United States, and a resident of the city of Buffalo, inthe county of Erie and State of New York, have inventeda new and usefulAutomatic Train Controhof which the following is a specification-L Thisinvention relates to railways and particularly to the control of anelectromagnet on the cars or.trains thereof, which electiomagnet mayoperate any suitable device for causing controlling of the train.

An important object of this invention is an arrangement andconstructionof train control including an electro-niagnet upon thetrain, wherebyonc trackway element alwavs acts to deenergize theelectro-magnet l 1 if it IS energized and another trackway element actsunder one condition to energize the electro-magnet and under otherconditions does not so act. Qther objects and vention will appearas thedescription, here- 'lnatter appearing. of the particular hysicalembodiment which has been seected to illustrate the principle o f theinvention, progresses, and the novel features of the invention will beparticularly included. in the claims hereto appended n i a The inventionconsists in the combination and constructions, embodyingthe principleofthe invention and particularly described in the specification and'pointedout in the claims for one particular physical: embodiment of theinvention In describlngthe prmciple of the invention, reference will behadto an illustrative physical embodiment illustrated by a singleschematic view in the drawing orining 21 art of this specification.which drawinp "illustrates the invention as applied to a car.

In the drawing used for illustrating the particular physical embodimentof the prim ciple of my, invention an ordinary rai road tie is shownat 1. Mounted on this tie in the usual-and ordinary manner are the rails-2. ;A car is illustrated as bein on the rails 2 by the showing of theordinary axle 3 and the wheels 4.

The car. which is designated as a whole as carries a relay R showndiagrammatireally as double wound having a winding 5 and mother winding6.

The relay R has an armature 7" which may be used in any well known andapproved manner for controlling the car. The

advantages of the in armature is shown as controllingan air brake'valve8 and a green lamp 9 and a red lamp 10.

The fcar C supports in any suitable or appropriate manner the shoebracket l1 carry mg the vertically 'reciprocntable plunger 12, and alsothe coil 13 is carried by the car.

Mounted adjacent to the rail in any suitable or appropriate manner is afixed ramp 14,;15 by mounting on the tie l. and 1 a coil 15,, as bymounting on ihctie l. The coil 15 may beculled an inductori The coil 15may be energized in any suitable or appropriate manner. (in the drawingthe legend indicates that the coil iscnr gi zed by a control of a trackcircuit or manuallfy in any appropriate manner.

I coil 15 is energized then nhcn*"car C )asses, a current is induced incoil '13 which mar be called a'receircr \rhich'ener gizes winding 5 ofrelay R and causes arn iature 7 to be raised to the positioirshown. Thismay be called the pick-up" circi itl The ramp 14 is so positioned thatplunger 12 drol sirom its raised position. as shown in the drawing whilethe Hunger is on ramp 14 th a lowe'r position )efore relav R is removedfrom the effect of coil 15. r

* \{Vheir )lungrr. l). drops. then the upper metallic lmtton 16 of theplunger hia kcs contact with both the springs 17 andltl.

,insulatingly mounted on shoc bracket ll. so

thatthe arnu tnrcT hcinp raiscd a circuit is formed as fol ows: Positircsidc f battery 19 wirevzll. coil 6 of relayli. wire llsspring 17.metallic button l6. spring l8. n'i re E22. armature 'i' and wire '23back to the negka tire terminalof. battery l5), This rircuitmain tainsrelay ll energized crcu after coil 13 has lllU\' t(l ana vfronr theiullucnce of coil- 1:") and so maintains armature T raised. This circuitmay be called the stick-up" irca-lit As there isa piclcup circuit forrelay R and a st'i'ck-up" circuit for rclay R. it is designated astir-k" relay in accordance with the usual nomenclature.

If the relay R is energized by the circuit throu; 'h armature 7 and thecar passes a ramp as 14 and a dccncrgizcd coil as if) it will be readilysccn that rclav it will be deenergized and armature T will fall toremain down until the car C passes a coil 15 which is energized.

When armature 7 is raised a cin-uit is formed through air brake valve 8prevent ing that valve from venting the train line the art and applyingthe brakes, the circuit being as follows: positive side of battery 19,wires 24 and 25, valve 8, wires 26 and 27, armature 7 and wire 23 to theother terminal of the battery 19. v

A circuit is also closed through neen lamp 9 when armature T is raisedas fol ows: positive side of'battery 19, wires 24, 28 and 29, lamp 9,wires 30 and 27, armature 7 and wire 23 to the other side of the battery19.

When armature T is in the lower position in circuit through the red lamp111 is formed as follows: positive side of battery 19, wires 24, 28 and31, lamp 10, wire 32, armature 7 and wire 23 to the other side ofbattery 19.

It will now be readily understood that under roper conditions, as clearconditions, the coi 15 will be energized. A car pass ing will have itsrelay R energized or if it is energized, it will be maintained energizedand lamp 9 will be li hted and the air brake valve 8 energized. eseconditions will be maintained by the bridging of springs 17 and 18 bybutton 16 after the coil 13 is rcmoved from the influence of coil 15.

It will further be understood that if car C passes coil 15 when properconditions prevail, for instance, danger conditions, then coil 15 willbe deenergized and consequently relay R will be deenergized by thecontacting and raising of plunger 12 by ramp 14. This will cause t egreen lamp to be extinguished. the red lamp to be lighted and the airbrake vabe 8 to be deenergized setting the brakes on the car in theusual and well known manner.

It will further be understood that the relay R ma be used as is wellunderstood in or any purpose desired and for which it is appropriate,and that its deenergization is accomplished by mechanical means of apermanent and fixed nature and that its ene'rgization is accom dished byindubti've means of a changeab e nature and its continued energizationis dependent upon I plbliminary action of the iln ucthe means and thesubsequent action of train carried means.

Althou one physical embodiment of the invention has been hereindescribed and illustrated, it is desired to have it understood that thephysical embodiment selected to illustrate the principle of theinvention does not exhaust the possible tangible the car; a "piclE'uphysical embodiments embodying the princi le of the invention.
